Chemical Structure

Ethyl 5-Bromo-8-carbamoyl-6-fluoro-2,3,4,9-tetrahydro-1H-carbazole-2-carboxylate CAS 1643156-20-0 chemical structure

Description

CATO supplies Ethyl 5-Bromo-8-carbamoyl-6-fluoro-2,3,4,9-tetrahydro-1H-carbazole-2-carboxylate (CAS 1643156-20-0), a certified reference material (molecular formula C16H16BrFN2O3, MW 383.21 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, Ethyl 5-Bromo-8-carbamoyl-6-fluoro-2,3,4,9-tetrahydro-1H-carbazole-2-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 383.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
